Description
技术领域
本发明属于药物学领域,涉及一类N-(1H-吡唑-5-基)嘧啶并吡唑-4,6-二取代胺类衍生物及其制备方法和用途。具体涉及如结构式I的一类化合物及其制备方法和在FGFR抑制剂中的用途,上述化合物具有显著的抗肿瘤活性。
背景技术
蛋白激酶为一类调节各种细胞功能的蛋白质。这是通过在蛋白底物上特定氨基酸的磷酸化而使得底物蛋白构象改变而完成的。构象的变化调节底物活性或者其与其他结合配偶体相互作用的能力。蛋白激酶的酶活性是指激酶往底物上添加磷酸根基团的速率。这可以通过测定被转化为底物的量和时间的函数来测定。在蛋白激酶的活性位出现底物的磷酸化。
酪氨酸激酶在蛋白底物上催化ATP的末端磷酸转化为酪氨酸残基的蛋白激酶的亚组。这些激酶在致使细胞增殖、分化和迁移的生长因子信号传导的传播中具有重要作用。
成纤维细胞生长因子(FGF)被认为是许多生理过程(如发育和血管生长过程中形态变化)的重要介质。目前存在超过25中德已知FGF家族成员。成纤维细胞生长因子受体(FGFR)家族包括是个成员,其各由胞外配体结合区、单跨膜区和细胞内胞质蛋白酪氨酸激酶区组成。在FGF刺激下,FGFR发生二聚作用和转磷酸作用,着导致受体活化。受体的活化足以恢复和激活特定的下游信号配偶体,所述下游信号配偶体参与各种过程如细胞生长、细胞代谢和细胞存活的调节(Eswarakumar,V.P.等,Cytokine&Growth Factor Reviews2005,16,139-149)。在对于肿瘤细胞增殖、迁移、入侵和血管形成等关键性的生活过程中,FGF/FGFR信号通路具有多效应作用,与人类癌症直接有关。
在多种肿瘤如膀胱、肾细胞和前列腺等中各种FGF的表达均有增加。FGF也是强有力地血管生成因子。各种FGF的激活突变与膀胱癌和多发性骨髓瘤有关,同时有文献证明受体在前列腺和膀胱癌有表达(Grose,R.等,Cytokine&Growth Factor Reviews 2005,16,179-186;Kwabi-Addo,B.等,Endocrime-Related Caner 2004,11,709-24).因此,靶向FGFR和FGF信号传导的治疗可以直接影响肿瘤细胞核肿瘤血管生成,FGF信号传导系统为具有吸引力的治疗靶点。

2.1细胞培养
2.1.1细胞复苏
实验前,超净工作台台面用紫外线照射30min。将水浴锅预热至37℃,将新鲜配制的培养基置于水浴锅预热。取出冻存的细胞,迅速将冻存管投入到已经预热的水浴锅中迅速解冻,并不断的摇动,使管中的液体迅速融化。约1-2min后冻存管内液体完全溶解,取出用含70%酒精棉球擦拭冻存管的外壁。吸取冻存管内细胞,转移至15ml离心管中,同时加入5ml预热完全培养基。500x g低转速离心3-5min,吸弃上清液。向离心管内加入10ml培养液,轻柔吹打制成细胞悬液。通过台盼蓝染色细胞记数并进行活力测定后,将细胞悬液加入10cm培养皿中,于含37℃/5%CO2培养箱中培养过夜。
2.1.2细胞培养与传代
细胞培养时所需的培养基以及细胞传代的比例参考细胞供货商细胞培养说明书。
2.2化合物处理
待测化合物用DMSO溶解后用完全培养基稀释至5倍的最终浓度(最终浓度为10μM)用于实验。在项目完成后,GenScript会保存客户样品储存液3个月,之后会做丢弃处理。
2.3CellTiter-Glo细胞活力检测方法
(1)接种细胞:
收集对数期细胞,调整细胞悬液浓度,在384孔板中接种40μl细胞悬液(2×104/mL),边缘孔用无菌PBS填充。
(2)将细胞板放在37℃/5%CO2培养箱孵育至贴壁,加入10μl 5x待测浓度的化合物。原则上细胞贴壁后即可加化合物,本研究采用的方法是铺好细胞孵育6小时后加入药物。
(3)细胞在37℃/5%CO2培养箱孵育,在24小时、48小时和72小时用倒置显微镜进行观察。
(4)读板:
72小时后每孔加入30μL每孔CellTiter-Glo反应混合物,将检测板振荡2-3分钟,室温孵育10min。在Pherastar(BMG labtech)读RLU值并保存数据。
2.4数据分析
Cell Growth inhibition%=100%×[1-RLU样品/RLU阴性],其中RLU样品为加化合物孔或阳性对照孔RLU值,RLU阴性为仅含DMSO的RLU值。运用GraphPad Prism 6.0软件进行数据分析。
检测16个化合物在10μM时对肿瘤细胞SNU-16及KATO III的生长抑制作用,每个浓度检测2个复孔。
上述实验结果证明:化合物的活性已经达到较高水平,本发明的N-(1H-吡唑-5-基)喹唑啉-4-胺类化合物均有很显著的抗肿瘤活性。
本发明并不局限于前述的具体实施方式。本发明扩展到任何在本说明书中披露的新特征或任何新的组合,以及披露的任一新的方法或过程的步骤或任何新的组合。
